Description

Cable terminal connects positioning fixture Technical Field The utility model relates to the technical field of railway power equipment installation, in particular to a cable terminal connector positioning clamp. Background Along with the rapid development of railway running towards high speed and high density, the requirements on the reliability of a railway power system are higher and higher. The railway power supply system mainly comprises a power supply network consisting of a power transformation and distribution substation, a through power line, a low-voltage power distribution line and power equipment facilities along the line, is responsible for the production, transportation and life maintenance power supply tasks of the whole railway, and provides reliable power guarantee for dispatching and commanding, communication signals, passenger service and other businesses.
